Maybe a purely mechanical conversion to file_operations would be a nice firststep, just so we can remove read_proc and write_proc? Taking scsi_proc.cas an example, this should be really straightforward and lets us getrid of the write_proc and read_proc callbacks from proc_dir_entry withouthaving to rewrite all the remaining drivers that use it.

Obviously, someone who understands the specific driver code better shouldthen clean up the code by converting to seq_file operations or somethingelse that is appropriate there.
